Image Display

NOTE: The liftgate must remain closed for correct operation of the video camera system.

The rear parking aid camera image is displayed by the FDIM when the transmission is placed in reverse. To determine the selector lever position and enable the rear parking aid camera display, the BCM sends the gear position message over the MS-CAN to the IPC serving as a gateway. The IPC then sends the message to the APIM on the I-CAN. The rear parking aid camera generates a video signal any time it receives voltage, regardless of the current configuration. If the rear parking aid camera is not configured properly, some features may be inoperative. The rear parking aid camera is supplied voltage when the ignition is on. When the rear parking aid camera is on, the video signal is sent from the camera to the APIM on shielded twisted pair wires. The APIM displays the image on the FDIM.

The following parking aid camera system features are configured by the driver using the FDIM:

Visual park aid alert -- this feature assists the driver to visually see the object causing the parking aid system to sound.
Manual zoom -- this feature assists the driver with connecting or towing a trailer and allows the driver to manually zoom closer to an object behind the vehicle.
Video camera delay -- this feature allows the driver to see the image behind the vehicle after the vehicle is shifted out of REVERSE. The image will not be displayed if the vehicle is shifted into PARK.

For each one of these system features, except the parking aid camera delay feature, the driver generated backup parking aid camera commands are sent from the FDIM to the APIM to the BCM. The BCM then sends the command to the rear parking aid camera via the LIN circuit. The rear parking aid camera then generates the requested feature on top of the video image and outputs the video signal to the APIM which in turn displays the video on the FDIM.

The rear parking aid camera delay feature is controlled within the APIM.
